History
Hillsborough was one of the five original counties identified for New Hampshire in 1769, and was named for Wills Hill, 1st Earl of Hillsborough, who was British Secretary of State for the Colonies at the time. The county was formally organized at Amherst on March 19, 1771.
In 1823, twelve townships of Hillsborough Country – Andover, Boscawen, Bradford, Dunbarton, Fishersfield (now Newbury), Henniker, Hooksett, Hopkinton, New London, Salisbury, Sutton, and Warner – became part of Merrimack County. The town of Merrimack along the Merrimack River in south-central Hillsborough County was not included in the newly formed county to the north. Hillsborough County's administrative functions were moved from Amherst to Milford in 1866, and then to the current seats of Manchester and Nashua in 1869.

Politics and government
In the 2012 presidential election, Time had listed Hillsborough as one of five critical counties affecting the outcome in the swing state of New Hampshire. Obama ended up winning with a margin of 50%–49%. Despite its more urban nature, Hillsborough County has historically been a more Republican leaning part of the state, although there is evidence to suggest that is changing. In 2020, Joe Biden and Jeanne Shaheen won Hillsborough County by a wider margin than they won statewide by. Biden also received the highest percentage of the vote for a Democrat since Lyndon Johnson's 1964 landslide, largely driven due to large swings to Democrats in the county's historically Republican suburban communities.
